This application is a continuation of U.S. patent application Ser. No.12/624,621, filed Nov. 24, 2009, incorporated herein by reference.

BACKGROUND OF THE INVENTION

This application has subject matter in common with U.S. patentapplication Ser. Nos. 12/318,471, 12/318,470, 12/318,473, 12/292,153,12/232,505, 12/232,035, 12/149,963, 12/149,964, 12/073,095, 12/073,889,12/007,076, 12/003,691, 12/003,809, 12/806,711, 12/806,285, 12/806,284,12/566,322, 12/527,628, 12/527,629, 12/498,874, 12/545,992, 12/527,631,12/502,661, 11/498,881, 11/255,981, 11/184,771, 11/152,063, 11/094,215,11/092,742, 11/092,741, and 11/094,155.

The current invention provides a projection assembly for a variety ofLED (light emitting diode) lighting devices, including seasonal lightstring, seasonal desk-top light, seasonal ornament, seasonal doordecorative item, seasonal garden light, seasonal outdoor lighting, LEDlighting fixture, LED track light, LED USB light, LED battery-operatedlight, seasonal tree-top light, seasonal wall light device, and seasonaloutdoor device. None of these light devices have a projection function.Instead, they just offer illumination. They are too limited forapplication and do not meet green concept. This invention enables aprojection assembly to be added-on or built-into the existing variety ofLED lights to not only can offer the original light function forillumination but also to add the ability to project an advertisement,seasonal image, promotion, message, electronic photo album, or otherdesired image to a preferred location.

The market place already includes a lot of projection clocks, projectionpens, an slide projection machines, but all of these known devices usevery complicated optics lenses.

The current invention applies an LED that has a diameter of 5 mm withsuper high brightness and low cost. This is not the same as otherconventional market items using 1 Watt LEDs that have a high cost andpower consumption. The updated LED used by the invention is from JapanNichia Co., which offers low power consumptions ¼ W and ½ W LEDs havingtop quality with a high brightness for a long period of time. This savea significant amount of expense and power compared with prior projectiontoys or, business projection machines using greater than 1 Watt LED.

The current invention also applies a most economical projection assemblywith as few as a single optics lens inside a tubular-housing to create along distance image on a desired surface such as a ceiling, walls,ground, garage door, front door, outdoor walls, or patio.

The current invention also provides an add-on or built-in projectionassembly for an existing LED light that can enhance the existing LEDlight to include additional functions without having a lot of toolingcharges. For example, the invention can be used to add functions toproducts such as an LED track light, LED seasonal light string, LEDlighting fixture, a plurality of LED light devices, and LED lightshaving more than one LED.

The current invention also provides a universal projection assembly thatcan be applied to a variety of LED lights. For example one standardprojection assembly according to the invention can be put into differentseasonal LED light devices including an LED light set, LED light string,tree top LED light, ornaments, Christmas tree ball LED light, front doorLED light, garden LED light, garage LED light, patio LED light, outdoorLED light, and LED track light. This will save a lot of R&D and toolingcharges because of the uniformity of the projection assembly.

The current invention also provides a special attachment means to allowpeople to add a projection assembly to one of the LEDs of an LED lightstring and that enables the projection assembly to be fixed at a certainangle, or adjusted to another angle at any time by adjustable attachmentmeans. This will allow the traditional seasonal LED light string to nolonger just save power consumption but also to deliver a seasonalmessage. A certain number of projection assemblies may be added-on orbuilt-into the normal seasonal light string, which can include (1) a 10piece LED light string or a 20, 30, 40 piece LED light string which mayuse battery power pack; (2) a 50 piece LED light string or 100 piece LEDlight string which may use 2.5 Volt input current, (3) a 35 piece LEDlight string or 70 piece, 105 piece, or 140 piece LED light string whichuses the 3.0 Volt current.

Furthermore, the current invention also can use the same concept toadd-on or build-in a proper projection assembly for an LED track lightor any LED light having more than one LED. The projection assembly canbe applied to any number from one to all of the lights in the tracklight, any number of which may be LED lights. This will very good forany existing track light because each light-unit can be added or removedfrom the track at any time. It will be appreciated that replacing any ofthe light sources to add a with a projection assembly will still fallwithin the current invention scope.

The projection assembly of the current invention may have a variety ofdifferent constructions, including (A) a fixed angle construction (B) a180 adjustable angle construction (C) a construction that provides 360degree rotation in an x-y plane with a predetermined degree of tiltingwith respect to the z-axis. The latter construction may be similar tothat described in the inventor's U.S. Pat. No. 7,618,150 and otherpatent applications of the inventor. In addition, it is noted that lightdevices with more than one light source are described in the inventors'U.S. Pat. No. 7,455,444, and that the current invention may also usemore than one LED or light source for the projection light device, withone or more LEDs having super strong brightness serving as a projectionlight source and other LED(s) or light sources providing at least theoriginal light device's existing light performance and function. Stillfurther, the current invention may also use the principles described incopending U.S. patent application Ser. No. 11/806,284, now allowed,which discloses the placement of more than one optics means in front ofthe LED(s) of a projection assembly for a related night lightapplication.

The current invention may use the principle, disclosed in a number ofcopending applications and patents of the inventor, of a “sealed-unit”which includes all electrical components and has its own safetycertification so as to eliminate the need for separate certificationwhen non-electrical elements are added to make a final light device. Thesealed unit may have any desired combination of LEDs, circuit means,sensor means, switch means, conductive means, and prong means, wires orpig-tail sets or conductive arrangements for connection to a powersupply.

At least one project assembly 85 is arranged to be attached to themain-object (80) and may incorporates a corresponding mechanicalconstruction (84 a) (84 b), electric circuit means (not shown), adigital data processor and accessories (not shown), and/or an electricdevice to provide a valuable appearance and function, such as fixedangle projection, (FIG. 16) (FIG. 19) (FIGS. 20,20A, and 20B) (Figs.page 32-34), adjustable angle projection (FIG. 17) (FIG. 18), aplurality of projections (FIG. 1) (FIG. 2) (FIG. 3) (FIG. 4), movingprojection (FIG. 19), motion projection (FIG. 19), automaticallychanging projection (not shown), single image projection (FIG. 8),projection of changeable images (FIGS. 20-20B) (FIGS. 21-24) (FIGS.25-27) (FIGS. 28-31), automatically changeable images (FIG. 19) andother desired functions. The optics lens assembly may be any combinationof optics means, including those disclosed in the inventor's U.S. patentapplication Ser. No. 12/318,470 and U.S. patent publication No.2009/0284960. The discussion of feature (9) at the beginning of thedetailed description also refers to a very good optics-lens assembly forlong distance projection of up to 10 feet, while short distanceprojection of less than 6 feet can use fewer lenses to save cost.

The main-object (80) of FIG. 8 and main object (80′) of FIG. 9 may beidentical. As shown in FIG. 9, The main-object (80′) incorporatesfinal-parts (90′) to make a finished product (90″) in the form of an LEDlight having a projection device. The LED light may be a seasonal lightstring (FIG. 7), seasonal desk-top light (FIG. 16), seasonal ornament(FIG. 40), seasonal door decorative items (FIG. 40), seasonal gardenlight (FIG. 16-1), seasonal outdoor lighting (FIG. 18), LED lightingfixture (FIG. 9), LED track light (FIG. 9), LED USB light (FIG. 5), LEDbattery operated light (FIGS. 3 and 6), seasonal tree-top ornament(FIGS. 2 and 4), seasonal wall light device (FIGS. 20, 20A, and 20B,21-24, and 35-38), or seasonal outdoor device (FIG. 20-20B, 21-24, and35-38).

As shown in FIG. 7, the projection assembly (76) (76′) (76″) can beadded onto any of LED light (71), light device (71′), or bulb (71″) byquick install-means (not shown) to enable a respective at least one LED(73″), light source (73′), or bulb (73) to be incorporated into thecorresponding at least one projection assembly (76) (76″) (76′). Theprojection assembly (76) (76′) (76″) does not need to have any lightsource of its own since the displays (79) are illuminated by the atleast one of LED (73′), light source (77″) or bulb (73) from the LEDlight onto which it is retrofitted. Thus, as shown in FIG. 7, at leastone of the main-objects (71) (71′) (71″) may have a projection assembly(76′) (76) (76″) with projection function incorporated into the samelight string, whether the string is a 50 piece, 100 piece, or35/70/105/140 piece string as described above.

The LED light (70) may be selected from a seasonal light string (FIG.7), LED track light device (FIG. 9), LED light fixture (FIG. 5), LEDlight device or LED light having more than one LED (FIGS. 17 and 39).

FIG. 17-1 also shows at least one projection assembly (17-1 a) that isadded onto or built into, and that incorporates an LED light's LED orother light source (17-1 b). An attachment means (17-1 c), (17-1 d),(17-1 e), or (17-1 f) enables the projection means (17-1 a) and the LEDor other light source (17-1 b) to have a desired orientation because theswivel base (17-1 c) is connected with two end swivel rods (17-1 d) anda swivel base (17-1 e) to permit 360 degree rotation about an axis andtilting of the front projection assembly (17-1 a) to project a desiredimage to a preferred location with correct size and sharpness.

As shown in FIGS. 21-23, and also FIG. 39, a projection device for avariety of light devices, includes at least one sealed-unit havingbuilt-in parts and accessories selected from LEDs or other lightsources, circuit means, power input-means, conductive means, a plug andwire, pig-tail socket and plug, quick electric connector, socket andplug, electric components, a mechanical projection angle adjustmentassembly, and/or means to change the original display. The sealed-unithas a geometric shape design and is powered by direct or alternatingcurrent through conductive means and circuit means to obtain a triggervoltage and current for the LED or other light source. The sealed-unitwith all the parts and accessories will turn on the at least one LED orother light source to project an image to a preferred location orsurface according to predetermined features, function, and performance.The sealed-unit must meet all safety standards and be safety testcertified so that it can be incorporated with other final parts such asthe projection assembly to make finished products without the need foradditional safety certification.

As shown in FIG. 16, the projection assembly may be a fixed angle typewhich has a left tubular housing member (16-8) and a right tubularhousing member (16-8′) having an original display (16-11) that includesa plurality of slides (16-12) arranged on a wheel (16-10). Wheel (16-10)is arranged to fit into a groove (16-9) (16-9′) to complete theslide-changing function. The front optics lens is precisely positionedso as to enable the original-display (16-11) to project an image havinga pre-determined size to a predetermined distance. The projectionassembly (as illustrated in the rectangular inset to FIG. 16) can bearranged to form a desk top candle light set. The flame portion has aprojection top (16-15′) and/or the base has two projection tops(16-15″)(16-15′″) to allow people to have a novel illuminated candlelight set with three additional projection functions during the holidayseason.

As shown in FIGS. 17 and 18, the projection assembly (18-5) is designedfor over 180 degree or continuous rotation. Two extended elasticelectric-contacts (18-3) (18-3′) on each half ball enable the ball tocontinuously rotate without any damage to the electric connectionbecause the contacts are resilient. The projection assembly (18-5) ofFIG. 18 is similar to projection assembly (17-7) of FIG. 17 and has atubular housing that allows a light source (17-7 a) to emit a light beamto a first optics lens (17-1 b) and cause all light source light beamsto be parallel to the original-display (17-7 c). The original-display(17-7 c) must be very precisely positioned relative to a second opticslens (17-7 d) so that the projected image from the original display willbe correctly displayed. If the distance is just slightly off, the imagewill look very bad and be out of focus.

FIG. 19 shows an arrangement of an original-display (19 a) in the formof a screen which has changeable original display data that iscontinuously or periodically updated. The screen (19 a) is connectedwith a plurality of data delivering wires (19-13) in such a way as toleave enough space to allow the data wires to be correctly installed andmake very good electric connections. In case of complicated and highvolume data delivery, the projection assembly requires a specialarrangement including a top tube (19-A) and lower tube (19-C). The lowertube (19-C) has a flat surface (19-3) with walls (19-4) that includeterminals or poles to tightly connect with the top tube portion. Theflat surface (19-3) and walls (19-4) form a recess to allow theoriginal-display (19 a) to fit with the space and offer sufficient spaceto arrange a lot of data wires (19-13). The original-display of thisembodiment is a screen (19-a) installed within a lower screen-holder(19-7) and top cover (19-8). The top cover (19-8) has one area (19-10)for a plurality of the screen's terminals (not shown) to connect withthe data wires (19-13) using pressure-means (19-12) to press and fastenthe wires (19-30 by fastening-means (19-11) (10-11′). This enables alarge amount of data wires (19-13) to be provided so as to correctlydeliver electric digital data to the screen and provide a changeable ormovable image with sufficient resolution that it can be projected by theprojection assembly to a desired location with a correct focus. Thechangeable digital data may be LCD display data, map data, TV imageforming data, or any digital data that people might want to enlarge byprojecting it to a desired location so that it can be viewed by morepeople.

FIG. 40 shows the illuminated ornament balls each of which has at leastone projection assembly inside the ball and a hanger to allow people tohang the illuminated ornament balls on a tree, door, handle bar, nail oranywhere people like. This is the best application to add a projectionassembly to an illuminated object because the object can be hung on orplaced on a desk top, allowing people to find the best position to get aclear image using a pre-set focus of the project assembly, so the costwill be very low. However, other applications or embodiments mayincorporate focus-adjustment of the top lens, for example by including amechanism that can change the focus by twisting the mechanism to changethe distance from the top lens distance to the display as necessary toform the clearest and sharpest image. Thus, an adjustable focus lensassembly will still fall within the scope of the current inventionscope. It will also appreciated that the projection assembly may befitted within either a base or ball of an illuminated waterball. Thoseskilled in the art will also appreciate that the image projected to adesired location is not limited to seasonal or holiday images but may,as shown in FIG. 41, be any kind of art, design, shape, advertisement,logo, promotion words, message, display, stencil, painting, movie, time,motion picture, digital game, or digital data display image.

As a result, the invention should not limited to the above-discussedpreferred embodiments. instead, all alternative, equivalent, samefunction, or replaceable skills, theories, arrangements, andconstructions, including any those discussed in the inventor's copendingprojection light applications, may still fall within the scope of thecurrent invention.
